String Functions in OpenSCAD

OpenSCAD doesn’t have built-in string manipulation functions like Go does. However, we can demonstrate some basic string operations using OpenSCAD’s echo function and concatenation operator. Here’s an example that shows some basic string operations in OpenSCAD:

// Define a function to print
function p(str) = echo(str);

// Main part of the script
p("Contains:  Not available in OpenSCAD");
p("Count:     Not available in OpenSCAD");
p("HasPrefix: Not available in OpenSCAD");
p("HasSuffix: Not available in OpenSCAD");
p("Index:     Not available in OpenSCAD");
p(str("Join:      ", "a", "-", "b"));
p(str("Repeat:    ", "a" * 5));
p("Replace:   Not available in OpenSCAD");
p("Split:     Not available in OpenSCAD");
p("ToLower:   Not available in OpenSCAD");
p("ToUpper:   Not available in OpenSCAD");

In OpenSCAD, string manipulation is quite limited compared to other programming languages. Here’s what we can do:

1. We define a function p() to mimic the fmt.Println() function in the original code.

2. Most string functions are not available in OpenSCAD, so we print “Not available in OpenSCAD” for these.

3. We can concatenate strings using the str() function, which is similar to the Join function in the original code.

4. We can repeat a string by multiplying it with a number, which is similar to the Repeat function in the original code.

To run this script, save it as a .scad file and open it in OpenSCAD. The output will be displayed in the console window.

ECHO: "Contains:  Not available in OpenSCAD"
ECHO: "Count:     Not available in OpenSCAD"
ECHO: "HasPrefix: Not available in OpenSCAD"
ECHO: "HasSuffix: Not available in OpenSCAD"
ECHO: "Index:     Not available in OpenSCAD"
ECHO: "Join:      a-b"
ECHO: "Repeat:    aaaaa"
ECHO: "Replace:   Not available in OpenSCAD"
ECHO: "Split:     Not available in OpenSCAD"
ECHO: "ToLower:   Not available in OpenSCAD"
ECHO: "ToUpper:   Not available in OpenSCAD"

Note that OpenSCAD is primarily a 3D modeling scripting language, not a general-purpose programming language. Its string manipulation capabilities are very limited compared to languages like Go or Python. If you need more advanced string operations, you might need to preprocess your data in another language before using it in OpenSCAD.
